Bredesen holds a 5-point lead over Blackburn among likely voters, 50 percent to 45 percent, the poll shows.

CNN’s poll marks the first major survey that shows Bredesen has extended his lead outside of a poll’s margin of error.

The NBC News poll showed Bredesen with a 2-point margin over Blackburn among likely voters, 48 percent to 46 percent.

Apart from being firmly onboard with the “Make America Great Again” agenda in a vast pro-Trump state, a recent Fox News poll showed Blackburn with a 3-point edge over Bredesen among Tennessee likely voters, 47 percent to 44 percent.

However, that poll may be slightly biased because 53 percent of its likely voter respondents identified as Republicans while just 35 percent identified as Democrats.
